No. The only perfect numbers below 100 are 6 and 28.
28 is a perfect number.
perfect square numbers are 16 and 25
How about 150*6 = 900 which is a perfect square because 30*30 = 900
The number 30 is a perfect number. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors, excluding itself. The proper divisors of 30 are 1, 2, 3, 5, 6, and 15, which sum to 30. However, it should be noted that 30 is actually classified as an abundant number because the sum of its proper divisors (1 + 2 + 3 + 5 + 6 + 15 = 32) is greater than 30.
No, 30 is not a perfect cube. A perfect cube is a number that can be expressed as the cube of an integer, such as (1^3 = 1), (2^3 = 8), or (3^3 = 27). The cube root of 30 is approximately 3.11, which is not an integer, confirming that 30 cannot be written as the cube of any whole number.
28 is a perfect number.
The two perfect numbers between 1 and 30 are: 6, 28
The number is 28.

The perfect number between 20 and 30 is 28. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors, excluding itself. For 28, the divisors are 1, 2, 4, 7, and 14, which add up to 28. Thus, 28 is the only perfect number in that range.

It is 28 I did that at school in year 6
int i; for (i=2; i<=30; i+=2) printf ("%d\n", i);
A perfect number is a whole number such that when you add up all of the factors less than that number, you get that number.There are only two perfect numbers less than 30. The first one is 6 since 1+2+3-6 next we see that 1 + 2 + 4 + 7 + 14=28 so 28 is the only other perfect number below 30.Euclid proved that 2p−1(2p−1) is an even perfect number whenever 2p−1 is prime.This works for 6 and 28 where p is a prime and is 2 and 3 respectively. Using this formula for p=5, the next perfect number is 24(25−1) = 496The next one is p = 7 where we have 26(27−1) = 8128.The next perfect number is 33550336 we get this with the prime 13.
